Concentration of Polycyclic Aromatic Hydrocarbons in Cereals, Pulses, Potatoes, and their Products

Estimation of concentrations of PAHs [benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, dibenzo(a,h)anthracene, benzo(g,h,i)perylene, indeno(1,2,3-c,d)pyrene] in cereals, pulses, potatoes, and their products available in Korean markets gave mean levels of 0.13, 0.08, 0.06, 0.03, 0.08, 0.15, 0.45, and $0.14{\mu}g/kg$, respectively, with recoveries between 82.6-106.6%. Methodology involved saponification and extraction with n-hexane, purification on Sep-Pak Florisil cartridges, and high performance liquid chromatography using a fluorescence detector.

곡류, 두류, 서류 및 그 가공품 중 다환 방향족 탄화수소 (polycyclic aromatic hydrocarbons) 화합물 함량

곡류, 서류, 두류 및 그 가공품 총 200건을 대상으로 benzo(a)pyrene등 8개 PAHs 화합물에 대하여 분석하였다. 시료 중 PAHs 화합물을 n-hexane으로 추출한 후 Sep-Pak Florisil cartridge로 정제한 후 HPLC-fluorescence로 분석하였다. 분석한 대상식품 중 PAHs 평균 함량은 각각 benzo(a)anthracene $0.13{\mu}g/kg$, chrysene $0.08{\mu}g/kg$, benzo(b)fluoranthene $0.06{\mu}g/kg$, benzo(k)fluoranthene $0.03{\mu}g/kg$, benzo(a)pyrene $0.08{\mu}g/kg$, dibenzo(a,h)anthracene $0.15{\mu}g/kg$, benzo(g,h,i)perylene $0.45{\mu}g/kg$, indeno(1,2,3-c,d)pyrene $0.14{\mu}g/kg$이었다.
